FINGER-NAIL CUTTER.v

SPECIFICATION forming part of Letters Patent No. 342,780, dated June 1,1886.

Application filed August Q4, 185.

Serial No. 1755245. (No model.)

To all whom it may concern,.-

Be it known that I, GEORGE I-I. CoATEs, a citizen of the United States,residing in forcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement in Finger-NailGutters, of which the following is a specification, accompanied bydrawings, illustrating a iinger-nail cutter embodying the severalfeatures of my invention, and in which- Figure l is an elevation withthe outer case shown in sectional view. Fig. 2 is a vertical sectionalview. Fig. 3 is an elevation showing the opposite side to that seen inFig. 1, and with the outer inclosing-casein section. Fig. iis asectional view of the cap. Fig. 5 shows the rotating sleeve. Fig. 6 is adetached view ofthe inner tube. Fig. 7 is a sectional view of a part ofthe blade. Fig. S is an edge view of a part ofthe blade. Fig. 9 is atransverse sectional view of the blade; and Fig. l() Shows a portion ofthe inner tube.

Similar letters indicate like parts in the several views.

My invention relates to the construction of the nailcutter itself, andalso to the handle or case for holding the cutter in position; and itconsists in the formation of a curved depres` sion arranged withreference to the cutter, sol as to facilitate its use, and in thelocking mechanism contained in the handle, whereby the blade of thecutter is rigidly heldin position, as hereinafter described.

A is a shell or case to which the tube B is attached at a. The tube Bextends the entire length of the shell A and contains thetang b of theblade C; A slot, c, is formed in the tube B, Fig. 6, through which apin, d, in the tang b passes. A sleeve, D, is placed on the tube B,having a slot, e, with the notches e e2 at each end ot' the slot e. Thetube AB has a pin, f, entering a short transverse slot, g, in the sleeveD, by which the sleeve D is held from sliding on the tube B, and isallowed a limited rotary motion.

In the upper end of the tube B, and on the side opposite the slot c, Iform a short slot, g', into which a pin, 7L, in the cap E, Fig. 4,passes, which serves to prevent the rotary motion of the cap E, butpermits alimited sliding motion. The cap E is closed at the top. Itslower end overlaps the upper end of the sleeve D, and a' pin, j, in thecap E enters a helical slot, lr, in the upper end -of the sleeve D. A

Between the upper end of the tube B and the cap E is a spiral spring, F,whose tensionxnaintains the pin h at the upper end of the slot g', andalso the pinj at the upper portion of the helical slot k, holding thesleeve D with the notches e and c2 coincident with the slot c in thetube B, and locking the pin d at each end of the slot c. By pressing thecap E downward, and compressing the spring F, the action of the pinj inthe helical slot k will rotate the sleeve D and bring the slot e in theSleeve D coincident with theslot c inthe tube B, releasing the piu l inthetang b, and allowing the blade U to slide the length of the slot e.

The blade C and talig b are made preferably of one piece of steel, andupon the dat sides ofthe blade lileteeth l are formed, and a mortise, m,is cut through the blade from edge to edge, the sides of the mortiseforming sharp cutting-edges at a a'.

In order to allow the edge ofthe finger-nail to be readily entered inthe inortise m and presented to the cutting-edges n a, I make a curveddepression, p, in the blade midway between the cnttingedges a a.

.I am aware that iingennail cutters have been made having a mortise in asteel blade, with the walls of the mortise forming cuttingedges with oneside of the blade. Such I do not now claim.

I am also aware that a handle having an inner tube carrying the tool hasbeen used, said tube having a slot in which a pin entered, and a sleeveinclosing said inner tube, havingaslot with notches for locking the pinat each end of the slot; but in such eases the inner tube turns,carrying the pin into the slot and causing a partial rotation of thetang, which is objectionable.

In my present improvement the inner tube is rigidly attached to theouter case, and the sleeve alone has a rotary motion, carrying thenotches e and e2 on the pin d, which has only a longitudinal slidingmotion.

Vhat I claim as of my invention, and desire to secure by Letters Patent,is-` IOC 1. In a fingernail cutter consisting of a metallic blade havinga mortise passing through the blade and forming cutting-edges with oneside of the blade, the curved concave depression p, formed in the side,making the cutting-edges and opening into said mortise, as and for thepurpose set forth.

2. The combination, Awith au outer shell or case, of an inner slottedtube, al sleeve turning on the inner tube and having a slot withlocking-notches and a helical slot, a cap overlapping said sleeve andcarrying arpin entering said helical slot in the sleeve, andaspriugapplied to said cap to hold it up in position to be depressed by thethumb, asand for the purpose set forth.

3. The combination, with an outer shell or lfixed inner tube and thesliding cap, whereby the cap is held up and the actuatingpiu held in oneeud of the helical slot, as and for the purpose Set forth.
